Set the steering gear to the middle position, dividing the full angle of rotation of the propeller shaft in half and aligning the mark on the end of the propeller shaft with the protrusion on the distributor housing.
By swinging the bipod, determine the presence of a gap in the engagement of the bipod shaft sector with the teeth of the ball nut. No gap is allowed.
If there is a gap, adjust the gap in the engagement, loosen the lock nut of the adjusting screw and by turning the adjusting screw of the pitman shaft, turning the adjusting screw clockwise, eliminate the gap in the engagement and tighten the lock nut. Tightening torque of the lock nut (26,7...33,0) Nm.
After adjustment, check the rotation torque of the propeller shaft:
- turn the propeller shaft to the extreme left position and measure the torque, rotation of the propeller shaft from right to left within an angle of 90°. The torque should be within 80...120 Nm;
- turn the propeller shaft to the extreme left position and measure the torque, rotation of the propeller shaft from right to left within an angle of 90°. The torque should be within 80...120 Nm;
- turn the propeller shaft to the middle position and measure the torque, rotation of the propeller shaft from right to left within an angle of 90°. The torque should be within 120...180 Nm.
The difference in torques between the torque in the middle position and the torques in the extreme positions should be no more than 60 Nm for one specific mechanism.
If necessary, repeat the adjustment.
Warning. Adjusting the clearance in the engagement of the steering gear without removing it from the vehicle is strictly prohibited. When adjusting the clearance, the steering gear must be in the middle position.
